imam er ORN EY manica .my ze, 193s UNITED STATES PAT-ENT ori-*ica METHOD F PRODUCING BOX 0R CARTON BLANKS BEARING PRINTED REISSUED over 9 NHV 20 Claims. (Cl. 93-36) My invention relates to an improved method of producing box or carton blanks, and also to the resulting box or carton.

An object of my invention is to economically produce box or carton blanks of improved appearance and finish.

An object of my invention is to produce box or carton blanks, bearing printed matter on opposing faces, in a manner whereby substantially 1o absolute register ofthe printed matter is obtained. Usually, such printed matter includes marginal or other outline impressions as well as advertising and other printed impressions, my invention attaining register of such marginal or other outline impressions as well as aligned and positioned relationship of the advertising and other printed impressions relative to the configuration of the box or carton when set up.

My invention is applicable to boxes or cartons 2g formed from integral stock.

My invention is particularly applicable to boxes and cartons embodying a fly leaf which is integral with the body of the blank.

In carrying out my invention, the printed matg5 ter is impressed in such number of varied colors and other impressions as may be desired to provide impressions on opposing faces of the box or carton as well as upon the ily leaf, if so desired. The printed matter, inclusive of the maximum number of desired colors and/or other impressions pursuant to the preferred forms lof my invention, are applied upon but one face of the web.

More specifically, a preferred form of my process comprises the feeding of a web through a suitable printing machine capable of impressing the desired printed matter in the desired number of colors upon one face of the web, the width of the web being substantially twice that of the nal blank, inclusive of the fly leaf, if any, the resulting single face imprinted web being then suitably folded upon itself, accompanied by the application of adhesive to bind the non-impressed faces of the web to one another as a composite web, and then blanking out such composite web in accordance with the outline of the desired box or car--v ton. the resultant blank being the box or carton in flat or collapsed status.

Another embodiment of my invention provides an insert ply of cardboard or relatively inexpensive, and therefore unfinished, sheet material which may also be in web form, the imprinted web being applied upon opposing faces of such insert ply.

The most preferred form of my invention, as to process, comprises the step of folding the printed web oppositely upon itself at both sides, to thereby locate the original side edges of the web within the resulting side edges of the .folded web, the original side edges advantageously being 'located along aline of longitudinal folding or scoring. 5 Accordingly, boxes and cartons and the like thus produced by my process possess the further distinctive advantage that the edges located at the thus oppositely folded web are rounded and finished as distinguished from severed, and 10 therefrom unfinished, edges. Such most preferred form of my invention is especially advantageous in the production of boxes or cartons embodying a ily leaf at one or both sides of the box or carton blank, the original impressed web 15 being in width substantially twice that of the resulting box or carton blank.

My invention also affords the control of the flexibility of a multiple ply by proper selection of the bonding medium for bonding the folded web,` zo either directly at its folded reverse face or upon opposite faces of an insert ply, such exibility g control being had, as for example, by adding glycerine or other ingredient of proper viscosity to the glue or other bonding medium. The reg5 sulting multiple ply, embodying such glycerine or equivalent lin the residue bonding medium, possesses a degree of flexibility controlled by the proper selection and proper proportion of the flexibility-controlling ingredient of the bonding 30 medium.

Further features and objects of the invention will be more fully understood from the following detail description and the accompanying dra ings, in which 35 Fig. 1 is a side elevation, largely diagrammatic, illustrating the step of passing a web of the material to be impressed through the indicated printing stage. This view also indicates the supplemental stage of scoring the web lengthwise to 40 facilitate the later operation of folding the web.

Fig. 2 is a detail view, on an enlarged scale, in plan of a portion of the impressed and scored web derived by the steps indicated in Fig. l.

Fig. 3 is a detail vertical transverse section on 45 line 3 3 of Fig. 2.

Fig. 4 is aside elevation, illustrating the step of folding theimpressed web upon itself.

Fig. 5 'is a Ytransverse vertical section oi' the blank resulting upon folding the impressed web 50 on opposite faces of an insert'ply.

Fig. 6 is a top plan view, largely diagrammatic, showing an impressed web folded pursuant to eitherrFigs. 4 or 5, in transit to and at the stage of blanking out the folded web to form individual 55 side and a fold-in flap at the opposite side.

Fig.V 7 is a side elevation of Fig. 6.

Fig. 8 is a transverse vertical section of an impressed web folded at a single, i. e., middle, line of scoring directly upon itself, that is, without an insert ply.

Fig. 9 is a vertical elevation, largely diagrammatic, viewed from a position opposite to that of Fig. 4, showing the stage of passing the insert material through an adhesive bath and the subsequent step of applying the impressed web on opposite faces of the adhesive coated insert ply.

Fig. 10 is a detail transverse section on line IU-Ili of Figs. 4 and 6.

Fig. 11 is a plan view of a box or carton blank having a ily leaf at one side of the blank.

Fig. 12 is a detail transverse section on line I2-I2 of Fig. 11.

Fig. 1 generally indicates at IB the web to beYY printed or otherwise impressed, preferably'supplied from a roll I I. At I2 is represented a regulation multi-color printing machine, applicable for multi-color printing and/orvother multiple impressions. At I3 is diagrammaticaily indicated any suitable scoring device, for scoring the web longitudinally to facilitate the subsequent operation of folding the impressed web upon itself at such scoring.

As to details appearing in Fig. 1, the roll II of web material is shown supported in a regulation bracket I 4; at I5 is indicated a regulation feedin roll device. At` I6, I1, I8 and I9, etc..are indicated color printing and/or. other impression units for applying the desired number of colored or other impressions. 'Ihe stated device I3 is employed jointly as the feed-out roller mechanism as well as to score the web as above set forth.

'At Illa, see Fig. 1 and Fig. 2, is indicated the impressed web, bearing the desired impressions, Iin this instance, see impressions 20, see Fig. 2, applicable to a box or carton for packaging and displaying chewing gum. At Ic, IIIe, are indicated two longitudinal lines of scoring, each of which may, as shown, (see Fig. 3), crimp the web I0a in direction upwardly relatively to the impressed face of the web.

As above indicated, the impressed web may be folded and bonded uponits non-impressed faces directly, see Figs. 4 and 8, or upon opposing faces of an insert ply 22, see Fig. 5, which insert ply may be fed between the folded web IIIa and the web Illa bonded at its non-impressed faces to such insert material 22.

The adhesive is applied, see indications 23, 23, Fig. 9, to the opposite faces of the insert material 22, in a suitable manner, as by passing a web of the insert material 22 through a bath of the adhesive, as indicated in Fig. 9,' that is, over a roll I, thence under the roll 52, submerged in the 'bath 53 of the adhesive, and discharged between the rolls 5l, 54, which rolls 5I,v 54, are provided with scrapers 55, 55. Advantageously. the folding and bonding of the impressed web Ila is had by a succession of pairs of pressure rolls, see 2l, 24, 25, 25, Figs. 4, 9, and 6.

'I'he resulting multiple ply web is passed from the stated pressure rolls to suitable blank-scoring means and blank-cutting means. As is indicated in Figs. 6 and '1, the blank scoring operation may be effected by a scoring roll 26 and its cooperating impression roll 26a., and vthe blank cutting operation may be effected by a cutting roll 21, and its cooperating impression roll 21a. Typical lines of scoring are indicated by 2l, see Fig. 6. Typical lines of severing are indicated by 29. 'I'he resulting blanks,see IIIB, Fig. 6, may be stacked as is indicated in Fig. '1, as upon ,a receding platform Il.

The thickness of the web of the ply insert v extends aboutthe stated edge when folded at the score lines Illc, see also Fig. 2. Obviously the Vedges resulting from folding at the score lines 2l,

folded-over web. Desirably, but not necessarily,v Y

the original edges I 6l are located substantially coincident with a scoring line 2l. 'I'he portion Ilia of the blank is a fold-in iiap.

^ The parts of the blank shown in Figs. 11 and 12 corresponding to like parts of the blank shown in Figs. 6 and 10 are designated by like reference characters. 'I'he blank of Figs. 11 and 12 has a fly leaf I Ild at one side, nam'ely, adjacent the edge Illd, the edge Ille at the opposite side of the blank being an edge of a side of the box or carton, which edge Ine is rounded" and finished.

In the employment of a web orother stock,v

folded uponitself and bonded directly at its nonimpressed face, pursuant to my invention, the web or other stock may be coated or otherwise finished on one face only, upon which finished face the printing or other impressions are applied, thus electing marked economy in the cost of web or other stock material in thatthe body of the web or other stock may' be selected of low cost and further that such web or other stock is of but one-half thickness, and may be paperas distinguished from board, as well 'as eifecting a saving by reason of the single operation of printing or impressing, namely, on one face only.

From the above it appears that my process eects positively exact register oi' all printed and/or other impressed matter appearing ultimately on opposite faces of the parts of the box nite economy in the production of box or carton blanks by affording when desirable the use of insert material of low cost, by reason of the absence of the requirement of finished faces for such insert material, and furthed, by reason that such insert material may provide the major thickness of the resulting blank. In contradistinction from my invention, the prior practice of employing a single web of paper board for the eventual box or carton blank, such board is required to be nished on both faces and therefore of relatively high cost. Furthermore, such prior practice requires the printing or other impressions to be applied on its opposite faces, therefore necessitating two separate printing or impressing operations, na-mely, for each face, and in addition introduces the most diicult, and commercially most expensive problem of seeking register of the printed matted appearing on the opposite faces of the single web or other stock and resulting blank.

My invention provides further for the control of the degree of exibility of the resulting multiple ply, whether with or without an insert ply, namely by proper selection and proper proportion of a flexible-imparting ingredient to the bonding medium. For example, glycerine may be added in proper proportion to an animal glue, or vegetable glues or other water solvent glue or other adhesive, whereby upon evaporation of the vaporizable constituent of the resulting bonding medium admixture, the glycerine or equivalent ingredient constitutes a part of the residue, i. e. resultant bonding medium. Similarly. other flexibility-imparting ingredient may be employed with the above stated or other types of glues or other adhesives.

Whereas, I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention.
